Gap
SPARK PLUG
• Inspect every 100 hours (6 months).
• Replace every 200 hours (12 months).
Standard spark plug : NGK DCPR6E
CARBON DEPOSIT
Check for a carbon deposit on the spark plug bases.
If carbon is present, remove it with a spark plug cleaning ma-
chine or by carefully using a pointed tool.
SPARK PLUG GAP
Use a thickness gauge to measure for correct spark plug gap.
Adjust to within the specified range if the gap is out of specifica-
tion.
Spark plug gap : 0.9 – 1.0 mm (0.035 – 0.039 in.)
09900-20803 : Thickness gauge
CONDITION OF ELECTRODE
Check the electrode for a worn or burnt condition.
If it is extremely worn or burnt, replace the spark plug.
Also, be sure to replace the plug if it has a broken insulator,
damaged thread, etc.
B
Confirm the thread size and reach when replacing the
plug. If the reach is too short, carbon will be deposited
on the threaded portion of the plug hole resulting in
possible engine damage.
Spark plug : 17.5 N
